PUSH TO START DUAL RELAY

摘要

A push to start dual relay having master electrical contacts which are closed when a push button is depressed. The master contacts control the power supplied to a control circuit which, in turn, controls the power supplied to two relays. When the push button is released and either one or both relays are energized, the master contacts remain in the closed position. When the push button is released and both relays are deenergized, however, the master contacts are allowed to open.
